The under surface of this ring is formedwith iicvci gcavtceth 24, so that it constitutes s nov clfgear meshingwith aV pinion 2.5, thc said pinion, being rigidly cuiried upon a.borissootsi driving shaft B.

',hesc openings src prscmbly ICGfour in numb-.1' and :nu mlziptcii iii receive rouiovoipic pins 3l, suchas iiustifated in Fig. 4. In this view the pins are represented inposition, a small portion olthe edge of the rotary beim,r rcprceentcd inIsection. thcec piney nrc in position, as shown in Fig. 4, it olv courseis evident that when the pinion 25 rotntcel the rolution ilnpnrled totbc ring .23 is also imparted to thil rotary tabled. Thiny would bc thi`relation ol the parte when the rotary is being' uned simply :is arotaryL In order to enable power to be employed for screwing thesections of pipe together or unscrewing the same, at a suitable point onthe ring .23 I provide oppoeitely-disposed lugs 32. '.lhese lu fs allordmeans for mount ing u bracket 33, t 1e construction of which is veryclearly shown in Fig. 3. The bracket coniprieee` a pair of diverginglegs 34, the lower extrei'nities whereof are formed withlaterally-projecting s ure 35, and these spurs are received in lateraopenings formed in the luge 32, as will be readily ui'iderstood. In thisway the bracket is removably supported in an upright position upon thering, as indicated in. Iiiv. 2. The upper portieri of the bracket isformed into a head 36, said head having a reduced neck, so thatoppositely dispoeed recesses or notches 37 are formed at this point.

Arranvement is iliade for locking the table 4 to the hed-plate. For thispurpose a pawl 38 is provided, which is preferably pivoted to one ol'the brackets 17, as indicated in Fig, 2, and the u )per extremity ofthis pawl is adapted to e thrown into a recess 3Q, formed on the undertace of the table, as indicated. In this way the table may be lockedagainst rotation in either direction.

One of the jaws 14 o posite that to which the elevator 1S is attacliopening 40, which is similar to the openingr 21, referred to above. lnthis opening 40 a removable pin 41 is placed, which projects upwardlybeyond the elevator, as indicated.

1 then apply chain-tongs or pi e-tongs 41 and 42. The tongs 41 are appheto the section 43 of the pipe which is to be unscrewed. As indicated inP ig. 2, these tongs are applied at such a height that the lever 44thereof may occupy one of the notches 37 upon the bracket 33. To thecollar 2() the ehain-tongs 42 are applied, and the lever 45 thereofdispoeed against the pin 41E.

With the parts arranged as described the pins 31 would be Withdrawn, so:is to enable the ring 23 to be rotated Without rotating the table 4.The table havin been locked by means of the pawl 38, the pinion 25 wouldbe driven so as to rotate the ring 23 in the proper direction. Thebracket 33 in this way is made to exert a force against the ch aintongs41 in a direction to unserew the pipe-section 43 from the collar 20. Thecollar 2O and the section of pipe therebelow is held against rotation bythe chain-tongs 42, which come WhenV ed is formed with an,
